WILLIAM A. SWEET, SYRACUSE, NEW YORK.

PASS-CONDUIT.

SPECIFICATION forming part of Letters Patent No. 510,450, dated December 12, 1893.

Application filed August 13, 1892. Serial No. 443,019 (No model.)

To all whom it may concern.:

Be it known that I, WILLIAM A. SWEET, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and' useful Improvements in Pass-Conduits, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to mechanism for automatically passing a metal bar, during the process of rolling, from one set of rolls to another, either with or without shifting or turning said bar on edge; or passing said bar automatically from the first set of rolls, into thesecond set, and from that into the third set, and so on, all without any manual labor except feeding the billet to make the first pass into and through the first set of rolls, or the first two passes through the rolls.

My object is to provide a train of rolls with means whereby part of all of the passes or repasses are automatically made from one set of rolls into and through the succeeding set or sets, without any manual handling, until the bar is partially or wholly rolled, by providing a curved conduit adapted to receive the partially rolled bar and guide and conduct it to, and pass it into the succeeding set of rolls, and another like conduit to pass it to the next set of rolls and so on, until the bar is finished, or the final pass may be made by hand, and whereby the movement of the bar through the rolls and conduits is continuous, and not intermittent, and so that, in fact, in rolling, a long bar can be passing through two or even three sets of rolls, and the intermediate conduits all at the same time; and in which the conduits are provided with means whereby the bar can be automatically turned on edge for edge rolling in one set of rolls and then turned flatwise for passage through the next set of rolls.

My invention consists in the several novel features of construction and operation here.

inafter described and which are specifically set forth in the claims hereunto annexed. It is constructed as follows, reference being had lto the accompanying drawings, in whichtop plan of part of a conduit. Fig. 4, is a transverse section on line wx, in Fig. 1. Fig. 5, is a like view on line y y, Fig. 3. Fig. 6, is a like View on line y y', Fig. 3. Fig. 7, is a like view on line y y", Fig. 3. Fig. 8, is a top plan view of the first pass-conduit in Fig. l, showing the conduit shifted, the dotted lines indicating its position in Fig. 1. Fig. 9, is a plan view of the bottom part of the conduit, showing the bar twisting incline. Fig. l0, is a perspective of one of the filling blocks, used between the ends of the conduit sections to till the space between their ends, when expanded in Fig. 1, and omitted in Fig. 2. Fig. 11, is a perspective of the central portion ot' the second conduit, detached from the base or body. Fig. 12, is a like view of one of the closures or lling blocks and-bolt used in the second conduit .between the ends of the conduit sections.

Fig. 13,is a like view of the slotted side rails,- sec'ured adj ustably tothe conduit sections and to which the closures are fastened.

A, is a train of rolls, shown here as consisting of separate sets of rolls -aa independently driven by a line of shafting carrying the drive-pulleys (not shown) and belting therefrom passing around the driven pulleys -bupon the drive shaft of each set of rolls. The rolls and their mouutings are all of ordinary construction, for single pass rolls, said rolls being provided with passes of any ordinary construction and of any desired form for flat rolling and edgewise rolling arranged alternately, or in any usual manner.

B-, is a conduit, consisting of a curved or semi-circular bed c, the ends of ywhich are detachably secured to the tables -dof two adjoining sets of rolls, upon which bed the conduit proper is detachably mounted. This conduit consists of curved and anged segfeed side of the next set in succession, which' receives the bar from one set and guides and conducts it to and into the next set, such feed through the conduit being entirely automatic and the pass of the bar therefrom into therolls being self feeding. As is shown in Figs. 5, 6 and 7, the bar is received iiatwise by the conduit, from one set of the rolls, and then IOO the Walls of said conduit being twisted a' quarter turn so that the channel is converted' from a horizontal one to a vertical one, the bar in its passage is turned 0n edge by the spiral of the channel, and in that position passes into the next set of rolls, for an edge pass through them; and then, leaving them on its edge, the spiral in the channel, either reverse to that in the preceding conduit, or not, turns the bar atwise again for its pass through the next set of rolls. In this man ner the bar is alternately rolled tlatwise and on edge.

The conduit sections fneach consists of a metallic casting (or forging) curved upon the radiusdesired, substantially as sho'wn in Figs. 4, 5, 6 and 7 in crosss'ection and placed upon the bedl--cin the position desired by means of boltsinserted through the slots -hin the bed,and` theearsnh upon the con# duit sections and' by' varying the position of the se'curing'bolts in the slotw'ays, the conduit' sectionsare adjusted to any positiondesired so as to" receive the bar from any pair of grooves in the pair ot'` rolls and passit tothe next pair of rolls;` and also to reduce the length of theconduit for passing small bars, or increase itslengthfor rolling larger ones. In Fig. 1, the first conduit is shown as extended or lengthened, and the space thus'cre` ated' between thesections--n` is illedby a pair of closures -cfea'ch comprising abase -l-, a vertical"wall-2- and a tlange-3- Substantially as shown'in Fig. 10, said flanges being usually about onehalf the Width of the" passage thrcughtheconduit sections at that point, and when inserted, the closure Walls and anges` coincide with the sidewalls and top flanges of said sections. In Fig. 8, the conduit sectionsare` drawn" in so that their ends meet, thus shortening the passage' throughthem and changing thepresentation of the sections to the rolls, and the closures are omitted. In Fig. l the secondconduit is shown as provided with a closure betweenthe ends of the sections whenset in to shorten the length ofthepass'ageas aforesaid; consisting of flanged closure blocks -kengagingon one side with a vertical plate ll-#overlap pingthe inner colnersof the sections, and on the other sidedetachabl y and adj ustably se-4 -6- and -7- of any number desired, and

screw bo1ts-8 inserted through the slots -6-' into' the closures, and bolts 9 inserted through the slots -7- into the outer sides of the sections. In this conduit the sections are adjustable in the same manner as in the rst'conduit, orby any equivalent manner. When expanded or set out to lengthen the conduit passage sufficient closures are used to ti-ll Wholly, or substantially, the open ing created between the sections and maintain the continuity of the passage.

As ameans of holding down the'inner ends of the closures angular straps -9- are shown secured detachably upon the bed by the bolts -l0- and havingtheir outer ends bearing upon the topszofsaid closures. central portion' of said channel may also be widened at or near' the cen'teroftheleurveof eachconduit, in order'to aiiord more' free`pas`- sage of the' bar through the channel.

ing and' making the passes; but the rolls" can be runat very high speeds,'s`uch` as would be very dangerous if nofconduitswere used; and consequently a train of" rolls will roll avery much larger'number of bars in agiven" time, than Where the passing is doneby hand, and

with little or`no damage at all to the operators;`

VVhatI'claim as myinvent-ion, and desire to" secure by Letters Patent, isf--v 1. A pass conduitconnecting oneset oflrolls 2. A pass conduit connecting one setof rolls" to another set, andincornbination therewith; consistingof a'bed, and conduit sectionshaving a continuouschannel therethrough partly flat, partly spiral, and partly vertical, and adjustably mounted upon the bed and meansto preserve the continuityof the'channelwhen the sections are separated.
